Powering:
As there are only 16 pins for the PC1602 modules, you need not connect power to the 17th pin.
GND and +5V can be taken from computer's internal power supply (use black wire for GND and
red wire for +5V)
WARNING! Be very careful connecting power supply. We do not recommend using external
power supplies. In no event shall Wandy liable for any hardware damages.
Note that there are some PowerTip PC2404A modules that have different pin-out. Compare:
From www.powertip.com.tw (probably newer one)
From www.actron.de (probably older one)
Some LCDs may be connected without resistors:
